Name
serialize_ocr_class_knnT_serialize_ocr_class_knnSerializeOcrClassKnnSerializeOcrClassKnnserialize_ocr_class_knn — Serialize a k-NN-based OCR classifier.
Signature
def serialize_ocr_class_knn(ocrhandle: HHandle) -> HHandle
Description
serialize_ocr_class_knnserialize_ocr_class_knnSerializeOcrClassKnnSerializeOcrClassKnnSerializeOcrClassKnnserialize_ocr_class_knn serializes a k-NN-based OCR classifier (see
fwrite_serialized_itemfwrite_serialized_itemFwriteSerializedItemFwriteSerializedItemFwriteSerializedItemfwrite_serialized_item for an introduction of the basic
principle of serialization). The same data that is written in a
file by write_ocr_class_knnwrite_ocr_class_knnWriteOcrClassKnnWriteOcrClassKnnWriteOcrClassKnnwrite_ocr_class_knn is converted to a serialized item.
The OCR classifier is defined by the handle OCRHandleOCRHandleOCRHandleOCRHandleOCRHandleocrhandle. The
serialized OCR classifier is returned by the handle
SerializedItemHandleSerializedItemHandleSerializedItemHandleSerializedItemHandleserializedItemHandleserialized_item_handle and can be deserialized by
deserialize_ocr_class_knndeserialize_ocr_class_knnDeserializeOcrClassKnnDeserializeOcrClassKnnDeserializeOcrClassKnndeserialize_ocr_class_knn.
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
Parameters
OCRHandleOCRHandleOCRHandleOCRHandleOCRHandleocrhandle (input_control) ocr_knn → HOCRKnn, HTupleHHandleHTupleHtuple (handle) (IntPtr) (HHandle) (handle)
Handle of the OCR classifier.
SerializedItemHandleSerializedItemHandleSerializedItemHandleSerializedItemHandleserializedItemHandleserialized_item_handle (output_control) serialized_item → HSerializedItem, HTupleHHandleHTupleHtuple (handle) (IntPtr) (HHandle) (handle)
Handle of the serialized item.
Result
If the parameters are valid, the operator
serialize_ocr_class_knnserialize_ocr_class_knnSerializeOcrClassKnnSerializeOcrClassKnnSerializeOcrClassKnnserialize_ocr_class_knn returns the value 2 (
H_MSG_TRUE)
. If
necessary, an exception is raised.
